An ideal gas is taken through the cycle `A rarr B rarr C rarr A` As shown in figure. If net heat supplied to the gas in the cycle is 5j. Find the work done by the gas in the process `C rarr A` in Joule (taken mole value)

Answer

5

Explanation

`W_(AB)=P Delta V, W_(BC)=0`
`q= DeltaU+(-W_(T))`
`:. DeltaU=0`
`:. q=-W_(T)=-[W_(AB)+W_(BC)+W_(CA)]`
`rArr 5=-[10+0+W_(CA)]`
or `W_(CA)=-5j`
